If you want to raise gardenia, you have to choose the right flowerpot first. Experience tells us that the clay basin has the best air permeability and water permeability, but its color value is low, and its outer wall is easy to grow moss, so it can be replaced by rough pottery basin.
However, the flowerpot cannot be directly placed in the tray. Stones should be placed between the tray and the flowerpot. Water should be added to the tray, and the bottom of the basin should not be stained with water, so as to not only moisten the gardenia, but also make the soil stagnant.
On the soil, we can refer to the soil matching of Gardenia original soil lump, which is usually the mixture of pine needle soil, garden soil and river sand. The proportion of river sand will be larger, which can prevent rotten roots to the greatest extent.
Gardenia jasminoides Ellis can be regularly poured with ferrous sulfate, or 3-4g oxalic acid can be used to adjust a bucket of water to slightly acidic. Note that the oxalic acid mixed water should be kept for one day before reuse, and the white sediment at the bottom of the bucket should be thrown away.
As for the watering method, observe that the surface of the basin soil is dry and then watered thoroughly. Pay attention not to let the basin soil harden. Loosen the soil before watering each time, otherwise it is easy to not be watered thoroughly.
South and North gardenia, the biggest difference is the air humidity, in addition to the tray water pad stone, you can also put a humidifier, control the air humidity between 60 and 70.
Gardenia is not suitable for sun exposure, especially in summer, the scattered light is enough for the normal growth of plants. In winter, the light is not strong enough to be sun exposed all day in nanyangtai, which is good for gardenia.
Fertilization should be less and more frequent. You can often pour some alum fertilizer and water. If you dislike trouble, you can occasionally apply compound fertilizer (several grains). When the flower bud is just emerging, you can apply some phosphate fertilizer, and stop fertilizing after flowering.
The selection of azalea basin is the same as that of gardenias. Ceramic basin is the first choice, followed by plastic basin. The bottom of the basin should also be padded up. You can use a wooden stick to frame the flowerpot to make the air hole empty.
On the soil, 30% of coniferous soil, 30% of garden soil and 40% of coarse sand can be used, 60% of peat soil, 30% of coconut bran and 10% of perlite can also be used.
Cuckoo likes water and is especially afraid of ponding. It's best to observe that the soil surface turns white at ordinary times. When carrying the flowerpot, it's obviously lighter, and then it's watered until there's water flowing out of the bottom.
Rhododendron and gardenia are acid loving flowers. Usually, they can retouch some peel water, ferment well for about 2-3 months, dilute 10 times with water, and water the flowers once a half month.
Rhododendron hate the sun exposure, but also can not lack of light, otherwise it will affect flower bud differentiation, in addition to the need for sunshade in summer, the spring and autumn can be put on the East balcony, the winter Nanyang platform all day sun.
If you want azalea to bloom more, you can also get water and fat. In March, June and September of each year, you can take 6G of bean cake and bone meal respectively, divide them into four parts and bury them on the edge of the flowerpot, and pour them into water.
